Save The Dramatics
A couple of years back, there was a case where a well-known manufacturer of latex paints was found to be destroying a local wetland with runoff. The state authority in charge of wetlands preservation took them to court. In a grandstanding effort to demonstrate to the judge that the chemical being discharged near the water could not possibly be toxic to the wildlife, a representative for the company brought a powdered form of the chemical into court.
They mixed it with a glass of water there and then, intending to drink it dramatically in front of the court. It backfired so, so badly. The glass, which was plastic, melted right there on the table. The case was settled out of court the same day.
